To all whom may concern:

-Bc it known that l, Josnrn l'nuissrrn, a citizen ol the French Republic, rrsiding at 7 Rue (lhorol, Paris7 France, haw invented certain new and useful improvements in a device [or automatically regulating the sul ply of steam to a gas-producer operating in conjunction with an internal-cornhust-ion vri-- gino, of which the following is a spcciliration.

This invention has rrncrenoe to a. device for regulating the supply of steam to gasprw ducers operating in conjunction with gas-cngines.

Gas-producers subject to thc direct suction of the gas-cnginc piston nrc Iarooming more and more recognized as the most desirable solution of the problem of olftainiug motive power ou account of thc ahsoncc of danger and their great economy, V which is such that no other practicable source ol' onorgy can compete against the: There are, however, still certain inconveniences to llo orcrcorne, among which may oc mentioned the inipcrd feet automatic regulation of the steam-sup ply to the producer and thc fact; thai the lip-- aratus for washing and ourii`y1`u; the gas as to he very bulky ii it is to be .e'l'iectivo Moreover, thc Wear and tcar on tiro opening or twyer for the entry of air and steam at the bottom of the producer rapidly sots up dislurilanoos in the regular action oi thopro ducer by reason of the increase in diameter of this opcning. Now these disadvantages are obviated hy the device shown in the annexed drawings, in which- Figure 1 represents the general construe l tion of the improved producer and purifier in vertical section on the liuc 1 l oi Fig. 2. Fig. 2 represents a horizontal section on the lino 3 3. 'Figa 3 and :i show, rcspectivcly, in transverse section and in lian a special hol-- low ring iecc ortwyer t ough which thi` steam and) air are admitted.

For thc purposc ol" illustration the regulating device 1s s town sot up in connection with a gas-producer .A and a purifier S, serving 'both as a condenser or cooler and also for ranged the cast-iron ring-piece E, wherein i thc twyer-openin f E', Figs. 3 and 4, throu h which tho air an( steam are drawn into .t e body A of the producer. The opening E is to he kopt at such a temperature that the metal is not liable to be attacked by the steam, and to this end the ring-gioco E is Inadc hollowJ as shown, and has a ownward projection or olli-zot, so that it will heV in conn tact with the eva orator D at thc points e e and will be there )y kept cool. It 1s further-n rnorc coolcd by the passage through or round its interior of the steam which it serves to deliver to thc gas-producer.

Tho steam produced in the evaporator D ,flows hythopassuge F to thc rc` ulating-valvo Ll and from there returns by t o passage F' into the ring-piece E, whence it passes out D T thc small holes H, so as to be drawn throu the opening E after being mixed with tie air.

The evaporator D has an upward projection on. its right corrcspondin to the downward projection on the ring Hence the superposition of the latter on the evaporator forms between the projections a passage I of rectangular scction, open at eac-h extremity. it is lo' the open ends of this assage I that the air enters the producer and) that the bottoni of tho furnace is cleaned out.

ln order that in a producer where the gas aspirated direotliT by the piston of the enzqinc the action of the latter may always be regular, it is necessary when the engine is working with a. full charge that the admission of steam should be at the maximum. When thc origine is Working with a variable char e, the proportion of steam passing into t e producer should 'he diminished accordingly and in )roportion to the smaller demand of 'work o the engine until finali the-introduction of steam shall be comp etely stopped, when the engine runs light Without taking in its charge. This ad'ustment is necessary if it be desired to aroid Vtoo great a drop in the temperature of the`"producerh1rnaoe due to a mixture (of air and steam) excessively rich in ing the steam issuing from the evaporator-D (for delivery into the bottom of the producer) to pase through the regulating-valve G, which is so set' that when the motor is running light it occupies the position indicated in Fig. 1 of foo , the shaft M opposite the wheel m, is connected which time its axis 2 presses on the tail end 9 ln this position all the steam l of the cheek-paw] 4, which thereby becomes escapes by the orifice g and never enters disengaged `from the wheel P.

At the following suction tho'valve Gwill therefore close a little farther still, and this will go on until the engine runs light, the omissions with the rod n2, which operates the valve G. This mechanism works as follows:

Each time that the suction-valve of the gas-engine is moved in a known manner to o )en said valve th'e rod J is pressed down and t c driving-pawl l drives the wheel P, thus closingr the valve G by means of the shaft M, the crank-disk 7, and the rod a2. The check. paw] 4 revente the hack movement of the wheel P until the pawl l has come back, at

At that time the wheel P will have returned to its point of starting, the communication between the passages F and li" will be interrupted, and no steam will be admitted to the producer,pl$ecause the iirst movement produced hy a single suction serves only o uncover the solid The brake-shoe 12 is pressed- IDO or misses being then, say, from three to four f part or wall separating the orifice F from the orifice F'. Hence by this means when the motor is in full work the admission of steam to the gas-producer is at a maximum. It dlminishcs graduali in proportion as the char e drawn in iminis les. The auctions also iminish and at le explained when t 1e motor is running gThe fuel or coal is introduced during working into the gas-producer by an apparatus or air-lock having a double closing arrangement, an the as passes from the producer by the passage 1, whereb it is led into the washer or scrubber S. latter is composed of'a mass or column of coke, se arated mtotwo arts by the walls or webss s which have left etween them a space a for the passage of the as comin from the reducer. These wallsie t cool y the Washing-water which is spraye on the column of coke, serve to cool the as, and the products of condensation fall into the waste-pan T along with any powder carried away by the wash-water. he gas issuing from the lower part of the condenser-space s ascends and traverses the column or pile of coke and finally llows out by the openings U on its way to engine.

The condenser and the washer or scrubber have been thus combined in one apparatus in orlr to diminish thc cost and the space remr q The apparatus shown may be modified when desirable in carrying the invention into practice without altering the general principle.
